:HP Victus 16-d0021sf - USB-C to DisplayPort stopped working after Windows update

[yosef95]

I have an HP Victus 16-d0021sf that has developed a display connectivity issue after a recent Windows update.

Problem:

- USB-C to DisplayPort connection no longer works with external monitors

- This worked perfectly before the Windows update

- Issue persists with multiple cables and different monitors

Troubleshooting already attempted:

- Updated all graphics drivers (Intel and NVIDIA)

- Tried different USB-C to DisplayPort cables

- Tested with multiple external monitors

- Enabled display-related options in Windows settings

- Used Windows display detection features

- Verified USB-C port works with other devices

I suspect the Windows update may have also updated the BIOS, potentially changing USB-C DisplayPort settings or compatibility.

Questions:

1. Are there known compatibility issues between recent Windows updates and USB-C DisplayPort on this model?

2. Was the BIOS updated as part of recent Windows updates for this laptop?

3. Are there specific BIOS settings I should check or reset?

4. Is there a recommended BIOS version for optimal USB-C DisplayPort functionality?

5. Should I attempt a BIOS rollback, and if so, what's the safest method for this model?

The laptop is otherwise functioning normally - this appears to be specifically related to USB-C video output functionaliassistanceqnk you for your assistance

Hi @yosef95,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP Victus 16-d0021sf laptop's USB-C to DisplayPort connection stopped working after a recent Windows update, despite the setup working previously. Let's go through a few steps to diagnose and resolve this issue.

1. Verify USB-C Port Functionality

Test with Other Devices: Connect a different USB-C device (e.g., external hard drive or smartphone) to the same USB-C port to ensure the port is functioning properly.

Check for Physical Damage: Inspect the USB-C port for any visible signs of wear or damage that might affect connectivity.

2. Check DisplayPort Alternate Mode Support

Confirm Support: Ensure your laptop's USB-C port supports DisplayPort Alternate Mode. Not all USB-C ports have this capability.

Consult Documentation: Refer to your laptop's user manual or HP's official specifications to confirm DisplayPort support.

3. Update Graphics Drivers

Intel Graphics: Visit the Intel Driver & Support Assistant to automatically detect and update your Intel graphics drivers.

NVIDIA Drivers: Use the NVIDIA Driver Download page to find and install the latest drivers for your NVIDIA GPU.

4. Check Windows Display Settings

Open Display Settings: Right-click on the desktop and select Display settings.

Detect Displays: Scroll down and click on Detect under the "Multiple displays" section to see if Windows recognizes the external monitor.

Adjust Display Settings: If the monitor is detected, adjust the display settings as needed.

5. Check for Windows Update Issues

Recent Updates: Go to Settings > Update & Security > Windows Update to see if any recent updates might have affected USB-C functionality.

Rollback Updates: If a specific update is identified as the cause, consider rolling it back by selecting View update history and then Uninstall updates.

6. Test with Different Cable and Monitor

Alternate Cable: Use a different USB-C to DisplayPort cable to rule out cable issues.

Different Monitor: Connect to a different external monitor to ensure the issue isn't with the original monitor.

7. Check BIOS Settings

Access BIOS: Restart your laptop and press the ESC key repeatedly to access the startup menu, then press F10 to enter BIOS.

Reset to Default: In BIOS, look for an option to Load Setup Defaults or Restore Defaults to reset any settings that might have been altered.

Save and Exit: After resetting, save the changes and exit BIOS.

I hope this helps.
